An Analysis of Highest Diurnal Precipitations Changes and Their Related to Annual Precipitations in Iran

Synoptic analysis of heavy precipitations of Kurdistan province

The aim of this study is synoptic analysis of heavy precipitations in Kurdistan Province during 1/1/1961 to 31/12/2010(18263days). By using two thresholds of extensively and intensity of precipitation, 107 days have been recognized. In temporal view, the selected days occurrences in wet seasons of year that start from October to June. By applying the principle component analysis on the sea leve...

Precipitations Prediction by Different Physics of WRF Model

In this article we have configured the nested grid WRF v.3.6 model for the Caucasus region. Computations were performed using Grid system GE-01-GRENA with working nodes (16 cores+, 32GB RAM on each). Two particulate cases of unexpected heavy showers were studied. Simulations were performed by two set of domains with horizontal grid-point resolutions of 6.6 km and 2.2 km. The ability of the WRF ...

Simultaneous X-band and K-band study of precipitations

One of the core research areas of the “Laboratoire de Météorologie Physique” (LaMP) at the “Observatoire de Physique du Globe de Clermont-Ferrand” (OPGC) is the study of clouds and precipitations, and their corresponding microphysical processes, both from the modeling and the observational point of vues. In order to improve its observation capabilities of precipitations, LaMP/OPGC has entered a...

Determination of Niobium precipitations in micro alloyed steels

Micro-alloyed High Strength Low Alloy steels (HSLA-steels) are widely used in civil construction, automobile and line pipe applications. They contain small quantities of alloying elements between 0,01 – 0,1 wt%, such as Niobium, Titanium, Vanadium, Aluminium and Nitrogen. These steels rely on thermo-mechanical rolling, a technique that simultaneously provides high strength, excellent toughness ...
